generally agree with -Farrell- (again

) -
higher priced cars are often off good value bcs they are (or rather shud be) in good trim and well maintained -
it can be VERY expensive to bring a lower priced car up to standards -
I love my M5touring but a 540iT (especially a M-package 6 gear manuell) is not doubt a more sensible car BUT it does NOT have a 'straight six', of course -
-
give me a wink when you find a M5touring you like, I just might have a history on that specific car in the registry -
-
the problem will be to find one in good shape, this is a rare car, if you are looking for 6-gear-car there were only 211 of them made and for a good specy you will have to be prepared to pay EUR 12.000 > 18.000 -
if you find one for EUR 6.000 -be warned- that can become a very expensive car with loads of problems unless you are a good ///M-mechanic yourself -
Good luck !
